Espresso Machines – Which One is Right For Your Home? The top espresso machines are simple to use, easy to clean and able to make rich and balanced shots. But how do you know which one is the perfect fit for your home? This Breville model is ideal for those who don't want to learn barista skills, but still want to enjoy great coffee at home. Pump-driven Pump-driven machines depend on an electric pump for the force required to brew espresso. These machines either accept water directly from the mains, as is the norm in commercial installations, or have a reservoir that must be manually filled (common for household espresso machines and smaller commercial espresso machines). The pumps used are often solenoid-piston designs that can create high pressure. Some espresso machines with pump-driven systems have a fixed flow rate, while others allow you to alter the pre-infusion or brewing temperature. They are the most well-known machines and are ideal for those who want a steady, high-quality cup coffee. These machines are easier to maintain and clean than other models, however they require electricity and a place near an outlet. There are two types of basic of semi-automatics and super-automatics. Semi-automatics allow you to control the amount of time the shot is pulled by using either a manual switch, or a feature that can be programmed. In addition, you can adjust the grind setting and tamp the coffee. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter and more consistent however they require a constant flow of pressurized water. In contrast, a vibrating pump starts off very quietly but can start to sound like a scream when the machine is fed with water. Both types have their pros and cons and you should choose the one that suits your needs best. Pump-driven machines also come in a variety of sizes and price. The most expensive machines are typically super-automatic and come with multiple boilers that separate the water for brewing as well as steaming. These models have heat exchangers which can be set at various temperatures to allow a variation in the flavor. This extra feature makes them an ideal choice for the busy home barista, it does raise the cost. The middle option is a semi-automatic which is a great value but doesn't offer as much consistency and versatility as other alternatives. Steam-driven A steam-driven machine uses simple mechanisms to create an intense espresso. In a container that is airtight, hot water is heated in order to create pressure, which is then transferred to the coffee grounds. This is similar to the process used inside a stovetop Moka pot. These machines are still in use today due to their affordability and compactness. However, these machines do not have the ability to produce the 9 bars of pressure needed for authentic espresso. This makes them ideal for those who are just getting started with home brewing or aren't concerned with making the perfect espresso. A very early example of a steam-driven machine is the 1878 compensation siphon balancing machine developed by German engineer H. Eicke. Steam is produced by this machine, which pushes boiling beans through an aerator. The water is released by heating from an open flame. This process produces a powerful shot, but doesn't meet the high standards of consistency that many espresso enthusiasts prefer. Luigi Bezzera patented improvements in 1901, which led to the next breakthrough. His design was able to lower the temperature of the boiler, allowing for more stable temperature and pressure control. Bezzera added an engine piston to make this machine semiautomatic. The only problem was the barista had to grind and measure beans manually. This led to the development of a pump-driven espresso machine. Contrary to older steam-driven machines that were heated with an open flame, the new kind of machine is equipped with an electric pump that is capable of producing the high pressure required for the brewing of espresso. The machines can take water directly from the cold water line common in commercial installations or they can utilize a separate tank filled with water by hand. The machines also come with two temperature settings, which are controlled by a button. One button activates the brew thermostat, and the other switch on the steam thermostat. This kind of machine is able to make consistent shots at less than what it costs when compared to steam-driven models. Semi-automatic Semi-automatic machines are the best option for those who want to make espresso quickly and efficiently. It takes away the need for barista training by automatizing the process of grinding, tamping, and extraction to ensure consistent results. It doesn't do all the work for you. You still have to grind the beans, tamp them down in the portafilter, and then push the water through. Many coffee lovers, both professional and amateur, prefer to use a semi-automatic machine for this reason, as they enjoy the feeling of being more involved in the brewing process. They are also less costly than their fully-automatic equivalents and are generally more reliable. espresso machines home of espresso machines are usually found in non-specialty coffee shops and at home of casual coffee lovers who are willing to pay more for convenience. Dual boilers allow the steam and brewing to remain separate. One is used for heating, while the other is used to prepare your favorite beverage. Some models come with a built in grinder that can save the user a lot of time. The built-in espresso grinder is usually limited in its settings, which can be a problem for those who wish to alter the process of making their own espresso. It is better to combine a semi-automatic espresso machine with an external grinding for full control over the size of the grind. If you're looking for a semiautomatic espresso machine, look for one with the lowest noise, a high-quality electric pump and a temperature controller that allows precise temperature regulation. The PID is typically used in high-end toasters and immersion circulators. It aids in stabilizing the brewing system by monitoring temperature fluctuations during the heating cycle. Additionally, a quality semi-automatic machine needs to have a sufficient steam wand to produce microfoam, and also be capable of switching between steaming and brewing modes easily (if it does not have two boilers). With all of these options, a top-quality semi-automatic espresso maker is an excellent choice for those who want to save the time and money of learning how to make cafe-quality drinks but still have fun experimenting with the process. Manual Manual espresso machines use levers to push pressurized water over a bed of finely ground coffee to produce highly concentrated shots. These machines are traditionally less expensive than semi-automatic and fully automated counterparts, making them a favorite for those who appreciate a fine cup of coffee. In contrast to automated espresso machines designed with ease of use in mind, manual espresso makers require more skill and attention by the operator to get the most of their potential. Making the right choice in a grinder, ensuring that the brew ratio is right, and understanding how to dose and tamp your grounds are just some of the things you'll need to know prior to making use of a manual machine. Although some people find the process of learning the manual espresso machine to be challenging and difficult but those with the right skills are able to make it worth the effort. Adrian Lini, CHOICE's expert barista says that if one has the patience and the right tools manual machines can make the best espresso. In recent times, the hand-operated espresso machine has improved in both its form and function. It now comes with more sophisticated features, such as digital pressure gauges that allow users to monitor pressure during extraction. Charles, who works at Flair Espresso, explains that these machines can also be connected with bluetooth devices to digitally plot graphs of flow rate which can help users understand how changing various variables during extraction can affect the overall result. There are two kinds of manual espresso machines including spring piston and direct. Direct levers have springs in their group heads, which helps to increase the pressure when making coffee. They're more expensive than spring-assisted units, but can still be easier to operate. Springs piston machines are limited to the steam valve within their group head. They are more user-friendly however they do not provide the same degree of control over the making process. The best type of machine will come down to personal preference and your budget. Whatever you decide to go with, a manual espresso machine will need a few essential equipment, such as kettles, a coffee grinder and a portafilter equipped with an adjustable dispersion screen made of metal.
